Underground projects require an emphasis on safety and precision to ensure high quality results. Diamond D constructs water lines, sewer lines, storm drains, and irrigation water deliver systems. Our projects have ranged from 4-inch ADS to 66-inch reinforced concrete pipe. Special requirements have included setting up bypass systems for sewage flows in excess of 1 million gallons a day, working in live traffic, installations in open agricultural fields and constructing projects in environmentally sensitive areas. Diamond D's sewer construction experience ranges from public works, commercial, and industrial systems to rural residential septic systems. Storm drain projects have varied from main trunk lines to agricultural culvert crossings.
